Hi Alan, This was a problem at fist for me. I was trying to use the wwnn and wwpn that I saw when the online was done. This is not what I use correct (as it only got errors on the vm console) I would use the real wwnn and wwpn for The tape drives I'm looking to get to .. correct ?

Sharing is simply a matter of giving an multiple LPARs access to different subchannels the same FCP chpid. N_Port ID Virtualization (NPIV) assigns each subchannel on the FCP chpid its own WWPN so that FC fabric access controls can be applied to each LPAR or guest individually at the subchannel level rather than at the chpid level (as is done on machines without NPIV). To use this support your FC switch must support NPIV.
